[0051] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0052] See also Figure 1 , showing the elevation view of the first embodiment of the independent shock-absorbing and reinforcement structural system for existing buildings of the present invention.

[0053] Figure 6 The diagram of the adjustable connection nodes of the reinforcement beam and the existing beam of the independent shock-absorbing reinforcement structure system for existing buildings of the present invention. Figures 1 to 6 As shown, the present invention is used for an independent shock-absorbing reinforcement structure system of an existing building. The existing building 10 includes an existing foundation, an existing column 11 vertically fixed to the existing foundation, and an existing beam 12 laterally fixed between two adjacent existing columns 11. The independent shock-absorbing reinforcement structure includes:
[0054] A reinforcement foundation 20 attached to the outside of the existing foundation and fixed to the existing foundation;
[0055] A reinforcement column 30 vertically fixed to the reinforcement foundation 20, the reinforcement column 30 being attached to the outer side of the existing column 11;
[0056] A column connector 60 connected to the reinforcement column 30 in a vertically adaptable movable and adjustable manner, the column connector 60 is fixedly connected to the existing column 11;
[0057] A reinforcement beam 40 is transversely fixed between two adjacent reinforcement columns 30 , and the reinforcement beam 40 is attached to the outer side of the existing beam 12 ;
[0058] A beam connector 70 connected to the reinforcement beam 40 in a vertically adaptable movable manner, the beam connector 70 being fixedly connected to the existing beam 12; and
[0059] A reinforcement support 50 is obliquely supported between two upper and lower adjacent reinforcement beams 40 .
[0060] Specifically, the existing building 10 is a concrete structure building to be reinforced, including an existing foundation, an existing column 11 and an existing beam 12 connected as a whole. The reinforced foundation 20, the reinforced column 30 and the reinforced beam 40 are steel frame structures connected as a whole, and their positions correspond to the existing foundation, the existing column 11 and the existing beam 12 respectively.
[0061] In actual construction, if the various parts of the two are completely fixed and connected, when the vertical deformation of the concrete structure building and the steel frame structure is not synchronized due to different materials, it is easy to generate a large additional shear force to damage their respective structures.
[0062] In the present invention, the reinforcement column 30 is fixedly connected to the existing column 11 through the column connector 60, thereby providing an out-of-plane fulcrum for the reinforcement column and reducing the out-of-plane calculated length of the reinforcement column. The column connector 60 can be vertically adaptively moved and adjusted relative to the reinforcement column 30, so that the reinforcement column 30 and the existing column 11 can be vertically adaptively moved and adjusted to release asynchronous deformation and prevent damage to the structure.
[0063] The reinforcement beam 40 is fixedly connected to the existing beam 12 through the beam connector 70 to support the existing building. The beam connector 70 can be vertically adaptively moved and adjusted relative to the reinforcement beam 40, so that the reinforcement beam 40 and the existing beam 12 can be vertically adaptively moved and adjusted to release vertical asynchronous deformation and prevent damage to the structure.
[0064] The steel frame structure composed of the reinforced foundation 20, the reinforced columns 30 and the reinforced beams 40 is arranged on the outside of the existing building 10 and is interconnected, and is used to provide lateral stiffness for the existing building 10 as an independent whole. Dampers are arranged inside the steel frame structure to provide damping energy dissipation for the structure, thereby improving the energy dissipation capacity of the existing building.
[0065] In addition, Chinese patent CN211313471U discloses an earthquake-resistant reinforcement substructure with an external additional frame steel support strong connection, which connects the additional frame column to the existing frame column, overcoming the shortcomings of the above-mentioned patent CN210482632U. However, due to the inconsistency in the allowable deformation capacity of the steel structure and the concrete structure, this method cannot give full play to the advantages of the strong vertical deformation capacity of the steel structure column. This leads to the following problems: the existing structure connected to the additional substructure also becomes part of the substructure that needs to be strengthened separately (see the "Technical Code for Energy Dissipation and Shock Reduction Reinforcement of Buildings" (T / CECS0547-2018) for details), which greatly increases the reinforcement workload. Steel components and concrete components form composite components, and the calculation and analysis of such composite components is also relatively cumbersome, and the promotion and utilization of this reinforcement method is not utilized.
[0066] The present invention connects the reinforcement column and the existing column through a column connector that can release vertical deformation, provides an out-of-plane fulcrum for the reinforcement column, reduces the out-of-plane calculated length of the reinforcement column, and thus solves the problem of the troublesome calculation and analysis and large reinforcement amount caused by rigidly connecting the additional substructure column and the existing structure column as a whole in the prior art. As a preferred embodiment of the present invention for an independent shock-absorbing reinforcement structure system for existing buildings, the column connector 70 is spaced apart from the reinforcement column 30; there is a spacing between the column connector 70 and the connection node between the reinforcement column 30 and the reinforcement beam 40, and the position of the column connector 70 is far away from the connection node, so as to avoid the conflict between the column connector 70 and the connection node during adaptive adjustment.
[0067] As a preferred embodiment of the independent shock-absorbing reinforcement structure system for existing buildings of the present invention, the column connector 60 is a sleeve mounted on the reinforcement column 30, the sleeve is fixedly connected to the existing column 11, and vertical adaptive adjustment is achieved by moving the sleeve up and down relative to the reinforcement column 30.
[0068] In one embodiment, in combination Figures 1 to 3 As shown, the reinforcement column 30 and the existing column 11 are arranged opposite to each other, and one side of the reinforcement column 30 is completely attached to the outside of the existing column 11. The sleeve is sleeved on the reinforcement column 30, and the sleeve can move vertically relative to the reinforcement column 30. When the reinforcement column 30 is a rectangular column, the sleeve is a rectangular tube with a suitable shape and size for limited connection. The reinforcement column 30 and the existing column 11 are limitedly connected through the sleeve, and vertical adaptive movement adjustment can also be performed.
[0069] A pair of ear plates 61 are formed on opposite sides of the sleeve. The ear plates 61 are clamped on opposite sides of the existing column 11 , and the ear plates 61 and the existing column 11 are fixedly connected by first anchor bolts 62 passing through the ear plates 61 .
[0070] In this embodiment, since the cross-sectional width of the reinforcement column 30 is smaller than the cross-sectional width of the existing column 11, the ear plate 61 includes a first plate perpendicular to the sleeve and a second plate perpendicularly connected to the first plate. The first plates of a pair of ear plates 61 are respectively located on opposite sides of the attachment surfaces of the existing column 11 and the reinforcement column 30, and the second plate is attached to the existing column 11, thereby clamping the existing column 11 to avoid lateral displacement.
[0071] This embodiment also includes a stiffening plate 63 which is vertically fixed to the first plate of the sleeve and the ear plate 61. The sleeve and the ear plate 61 are connected by the stiffening plate 63 to increase the stiffness of the sleeve outside the plane of the independent shock-absorbing reinforcement structure, thereby providing sufficient out-of-plane support for the reinforcement column 30.
[0072] In another embodiment, the combination Figures 1 to 5 As shown, the reinforcing column 30d is provided at a corner portion of the outer side of the existing column 11d, and one side surface portion of the reinforcing column 30d is attached to the outer side of the existing column 11d.
[0073] The sleeve is sleeved on the reinforcement column 30d. The sleeve can move vertically relative to the reinforcement column 30d. A pair of ear plates 61d are formed at the corners of the sleeve. The ear plates 61d are clamped on both sides of the existing column 11d, and the ear plates 61d and the existing column 11d are fixedly connected by passing the first anchor bolt 62d.
[0074] This embodiment also includes a stiffening plate 63d vertically fixed to the first plate of the sleeve and the ear plate 61d. The sleeve and the ear plate 61d are reinforced by the stiffening plate 63d to increase the stiffness of the sleeve outside the plane of the independent shock-absorbing reinforcement structure, thereby providing sufficient out-of-plane support for the reinforcement column 30d.
[0075] As a preferred embodiment of the independent shock-absorbing reinforcement structure system for existing buildings of the present invention, a vertical oblong hole is opened on the mounting surface of the reinforcement beam 40; the beam connecting member 70 is a bolt passed through the oblong hole, and is fixedly connected to the existing beam 12 by the bolt passing through the oblong hole, and the bolt moves up and down in the oblong hole to realize vertical adaptive adjustment.
[0076] Combination Figure 6 As shown, the oblong hole has a certain length in the vertical direction, and the bolt can move up and down in the oblong hole, so that the existing beam 12 fixed with the bolt can be vertically fine-tuned relative to the reinforcement beam 40.
[0077] As a preferred embodiment of the independent shock-absorbing reinforcement structure system for existing buildings of the present invention, a fixing plate 71 is attached to the surface of the existing beam 12, and the fixing plate 71 and the existing beam 12 are fixedly connected by passing through a second anchor bolt 72; the fixing plate 71 is fixedly connected to one end of the bolt.
[0078] The second anchor bolt 72 passes through the fixing plate 71 and the existing beam 12 and the pad 73 attached to the existing beam 12 and is then fixed by a nut. The reinforcement beam 40 and the fixing plate 71 are attached to each other with a smooth attachment surface to facilitate relative movement, so as to avoid damage caused by asynchronous vertical deformation of the reinforcement beam 40 and the existing beam 12, so that only horizontal force is transmitted between the two.
[0079] As a preferred embodiment of the present invention for an independent shock-absorbing and reinforcing structural system of an existing building, refer to Figure 6 This is a connection node diagram of the second position of the reinforcement beam and the existing beam of the independent shock-absorbing reinforcement structure system for existing buildings of the present invention. Figures 1 to 6 As shown, the attached surfaces of the reinforcement beam 40 and the existing beam 12 are welded to form a plurality of welds arranged at intervals, and the distance between the first weld 41 close to the existing column 11 and the reinforcement column 30 is greater than or equal to the set distance.
[0080] The distance between the first weld and the reinforced column 30 is relatively large, and the set distance needs to be sufficient to release the vertical deformation. The vertical deformation difference between the reinforced column 30 and the existing column 11 is released by the bending deformation of the reinforced beam 40 and the existing beam 12 within the above distance, thereby avoiding excessive shear force at the supports of the reinforced beam 40 and the existing beam 12 to cause structural damage.
[0081] By releasing the vertical deformation difference between the reinforced column 30 and the existing column 11 as described above, the existing building weakly connected to the reinforced structure is not required as a substructure, and no special verification and reinforcement is required.
[0082] Specifically, the first weld of the reinforced beam 40 and the existing beam 12 close to the existing column 11 is far away from the reinforced column 30, and the distance between the first weld and the reinforced column 30 generally needs to be greater than or equal to the set distance, and the set distance can generally be 4 to 5 times the cross-section of the reinforced column 30. In this embodiment, the set distance is 1000mm. Under the premise that the cross-sectional area remains unchanged, the reinforced beam 40 can adopt a cross-sectional form with weaker vertical bending stiffness (such as an H-shaped cross-section with the flange placed vertically) between the first weld close to the reinforced column 30 and the reinforced column 30 to further increase its ability to release vertical deformation.
[0083] As a preferred embodiment of the present invention for an independent shock-absorbing and reinforcing structural system of an existing building, Figure 1 As shown, a first damper is installed in the reinforcement support 50. The two reinforcement supports 50 are symmetrically arranged and the tops are fixedly connected to the corresponding reinforcement beams 40 through the mounting member 51. In this embodiment, the reinforcement support 50 has two functions. On the one hand, the first damper provides damping energy dissipation for the reinforcement structure to improve the energy dissipation capacity of the structure. On the other hand, the first damper is obliquely supported between the upper and lower adjacent reinforcement beams to enhance the support strength and stability of the overall steel structure.
[0084] The reinforcing support 50 can be a single oblique support, or a pair of oblique supports that are relatively symmetrically arranged.
[0085] As a preferred embodiment of the present invention for an independent shock-absorbing and reinforcing structural system of an existing building, refer to Figure 8 This is a vertical view of the second embodiment of the independent shock-absorbing and reinforcing structural system for existing buildings of the present invention. Figure 8 As shown, when the reinforcement beam and the existing beam are connected through oblong holes and bolts, the reinforcement support 50a is a steel structure support; the tops of a pair of reinforcement supports 50a are connected through a mounting member 51a; a second damper 52a is installed between the mounting member 51a and the corresponding reinforcement beam 40a to provide damping energy dissipation for the reinforcement structure and improve the energy dissipation capacity of the structure.
[0086] In this embodiment, the reinforcement support 50a and the second damper 52a are different structures. A pair of reinforcement supports 50a are symmetrically arranged relative to the vertical center line of the reinforcement structure and are fixed at the top by the mounting member 51a, so the structure is stable.
[0087] See also Fig. 9 This is a elevation view of the third embodiment of the independent shock-absorbing and reinforcing structural system for existing buildings of the present invention. Fig. 9As shown, when the reinforcement beam and the existing beam are connected by oblong holes and bolts, the reinforcement support 50b is a steel structure support; the tops of a pair of reinforcement supports 50b are connected by a mounting member 51b; the mounting member 51b is fixedly connected to the corresponding reinforcement beam 40b above; third dampers 52b are respectively installed on the opposite sides of the mounting member 51b, and the other end of the third damper 52b is fixedly connected to the corresponding reinforcement beam 40b above, and the third damper 52b is used to provide damping energy dissipation for the reinforcement structure, thereby improving the energy dissipation capacity of the structure.
[0088] In this embodiment, the reinforcement support 50b and the third damper 52b are different structures. A pair of reinforcement supports 50b are symmetrically arranged relative to the vertical center line of the reinforcement structure and the tops are fixedly connected by the mounting member 51b, so the structure is stable.
[0089] As a preferred embodiment of the present invention for an independent shock-absorbing and reinforcing structural system of an existing building, refer to Fig.10 This is a elevation view of the fourth embodiment of the independent shock-absorbing and reinforcing structural system for existing buildings of the present invention. Fig.10 As shown, when the reinforcement beam and the existing beam are connected by oblong holes and bolts, the reinforcement beam 40c includes a pair of reinforcement beam units which are laterally symmetrically arranged and have a spacing therebetween, and a third damper 51c is installed in the middle of the pair of reinforcement beam units; the reinforcement support 50c is a steel structure support, and the tops of the pair of reinforcement supports 50c are respectively fixed to the corresponding reinforcement beam units.
[0090] Specifically, the reinforcement beam unit, the reinforcement support 50c and the corresponding reinforcement column 30c are connected to form a triangular structure with good stability. The tops of the two bilaterally symmetrical triangular structures are connected by the third damper 40c. The above situation can only be used for the connection between the reinforcement beam and the existing beam through the oblong hole and bolt form.
[0091] The beneficial effects of the independent shock-absorbing and reinforcing structural system of the present invention for existing buildings are as follows:
[0092] In the present invention, the reinforcement column is fixedly connected to the existing column through the column connector, thereby providing an out-of-plane fulcrum for the reinforcement column and reducing the out-of-plane calculated length of the reinforcement column. The column connector can be vertically adaptively moved and adjusted relative to the reinforcement column, so that the reinforcement column and the existing column can be vertically adaptively moved and adjusted to release asynchronous deformation and prevent damage to the structure. The reinforcement beam is fixedly connected to the existing beam through the beam connector to support the existing building. The beam connector can be vertically adaptively moved and adjusted relative to the reinforcement beam, so that the reinforcement beam and the existing beam can be vertically adaptively moved and adjusted to release vertical asynchronous deformation and prevent damage to the structure.
[0093] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
